Description

Technical Field

[0001] This utility model relates to the field of wheel technology, specifically to a wheel suitable for heavy-duty engineering vehicles. Background Technology

[0002] Specialized vehicles for mine rail transport belong to the category of heavy-duty engineering vehicles (such as freight cars and material cars). They need to operate in the narrow and harsh environment of underground roadways. Their core moving mechanism is the mine car wheelset, which mainly consists of wheels, axles, bearings, and sealing materials. It is responsible for bearing the weight of the mine car and enabling track movement. When transporting bulk materials such as coal, ore, and waste rock, mine cars are easily exposed to coal slurry, dust, and acidic or alkaline impurities. Furthermore, the high-frequency vibration caused by uneven tracks further aggravates component wear.

[0003] In the prior art, such as the patent with publication number CN219969312U, a reinforced mining wheel is disclosed. By installing a reinforcing mechanism between the wheel axle and the mining wheel, including a collar, a fixed ring, a spring, a movable ring, a limiting rod, an end ring, a ring groove, and a rubber ring, the spring maintains the sealing effect, and the steel ring can be disassembled and replaced through the combined mechanism, thereby reducing maintenance costs.

[0004] However, the above technical solutions still have shortcomings: First, the sealing structure relies on ordinary springs to provide contact pressure, and the elastic fixation cannot adapt to the radial runout or surface wear of the wheel. The rubber ring is simply plugged in and is prone to loosening. Moreover, the hydrogenated nitrile rubber has insufficient corrosion resistance, and coal slurry water can easily penetrate into the bearing, causing wear. Second, the gap between the limit rod and the collar is not protected, and impurities can easily enter and cause jamming. The collar is only plugged in and is prone to axial displacement, which can damage the alignment of the sealing surfaces. Third, the fixing bolts between the steel ring and the wheel body are prone to loosening due to vibration. The mating surfaces of the slot and the block are prone to rust and jamming. In addition, the steel ring is not wear-resistant and has a high replacement frequency, which increases maintenance costs and downtime. Fourth, the accumulation of coal slurry water in the sealing area can easily break through the sealing layer, exacerbating the risk of failure.

[0005] Therefore, it is necessary to optimize the structure based on the original reinforced mining wheel to improve sealing reliability and structural durability. Utility Model Content

However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0017] See attached diagram. Figures 1 to 3 In this embodiment, a wheel suitable for heavy-duty engineering vehicles includes a wheel axle 1 and a wheel 2, with a reinforcing mechanism 3 installed between the wheel axle 1 and the wheel 2. The reinforcing mechanism 3 includes a collar 301, a fixed ring 302, a disc spring assembly 303, a movable ring 304, a limiting rod 305, an end ring 306, a ring groove 307, a rubber ring 308, a dustproof sealing ring 309, and a set screw 310: The collar 301 is sleeved at the end of the wheel axle 1, and the set screw 310 screwed on the side tightens the surface of the wheel axle 1 to prevent the collar 301 from shifting axially; the collar 301 is fixedly connected to the fixed ring 302 on the side facing the wheel 2, and the movable ring 304 is connected inside the fixed ring through the disc spring assembly 303. The disc spring assembly is composed of 2-5 disc springs stacked together, which has better anti-flutter ability than ordinary cylindrical springs and can adapt to the radial runout of the wheel; An end ring 306 is installed at the end of the movable ring 304. The outer circumference of the end ring has 4-6 inclined guide grooves at 10°-20° to guide the accumulated coal slurry water to the outside and prevent liquid seepage. The inner side of the annular groove 307 on the surface of the end ring 306 has an annular protrusion 3070, and the inner side of the inserted fluororubber ring 308 has an annular groove. The two are interference fit to prevent the ring from vibrating and loosening. The fluororubber material is oil-resistant, acid-resistant, and alkali-resistant, and has a long service life.

[0018] The limiting rod 305 at the end of the movable ring 304 extends through the disc spring assembly 303 to the collar 301. The surface is chrome-plated to improve rust resistance and wear resistance. The dustproof sealing ring 310 in the limiting hole of the collar can prevent coal slurry and dust from entering the mating gap, avoid the limiting rod from getting stuck, and ensure that the movable ring 304 moves normally with the spring force. Preferably, the dustproof sealing ring 310 is a Y-type sealing ring.

[0019] In the above scheme, the combined mechanism 4 is a detachable wear-resistant component, including a wheel body 401, a slot 402, a steel rim 403, a locking block 404, a threaded hole 405, a bolt 406, a tungsten carbide wear-resistant layer 407, an arc-shaped protective edge 408, a double-layered self-locking washer 409, and a slag discharge hole; the wheel body 401 is fitted with a steel rim 403 around its outer periphery, and the rail contact surface of the steel rim 403 is overlaid with a 3-5mm thick tungsten carbide wear-resistant layer 407, which has high hardness and impact resistance, and can extend the service life of the steel rim 403; the arc-shaped protective edges 408 on both sides of the steel rim 403 can prevent the steel rim 403 from directly impacting the rail when the mine car deviates, reducing edge deformation. The groove 402 of the wheel body 401 and the locking block 404 of the steel rim 403 are positioned together. Both mating surfaces are hot-dip galvanized for rust prevention. The slag discharge hole at the bottom of the groove 402 can discharge the incoming coal slurry water and dust to prevent rust and jamming. The threaded hole 405 of the wheel body and the steel rim 403 are fixed by bolts 406. The bolts 406 are fitted with double-layered self-locking washers 409 and coated with anaerobic anti-loosening adhesive to prevent vibration and loosening.

[0020] The working principle of this embodiment is as follows: When assembling the reinforcing mechanism 3: embed the dustproof sealing ring 309 into the limiting hole of the collar 301, fit the collar 301 onto the end of the wheel axle 1, and tighten the set screw 310 to secure it against the surface of the wheel axle 1; stack several disc springs in sequence inside the fixed ring 302 to form a disc spring assembly 303, and then insert the movable ring 304 into the fixed ring 302 so that the limiting rod 305 passes through the disc spring assembly 303 and into the dustproof sealing ring 309 of the collar 301; align the annular groove 3070 of the fluororubber ring 308 with the annular protrusion of the annular groove 307 of the end ring 306, and fix it with an interference fit; then fix the end ring 306 to the end of the movable ring 304 to ensure that the end ring abuts against the surface of the wheel 2.

[0021] When assembling the combined mechanism 4: deposit a 3mm thick tungsten carbide wear-resistant layer 407 on the track contact surface of the steel ring 403 to ensure uniform welding without pores; align the locking block 404 on the inner wall of the steel ring 403 with the locking groove 402 of the wheel body 401, and after locking it in, adjust the position of the steel ring 403 so that the steel ring 403 is aligned with the threaded hole 405 of the wheel body 401; apply anaerobic anti-loosening adhesive to the threaded surface of the bolt 406, put on a double-layered self-locking washer 409, and screw it into the threaded hole 405 for fixation.

[0022] During use: the elasticity of the disc spring assembly 303 keeps the end ring 306 in contact with the surface of the wheel 2, the guide groove guides the coal slurry water out, and the fluororubber ring 308 achieves sealing; when replacing the steel ring 403, unscrew the bolt 406, and because the slot 402 has a slag discharge hole, the steel ring 403 can be easily removed and replaced without force disassembly.

[0023] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
